Dr. Zooch Saturn V Build Step 6 Shaping the Engine Fairing

An earlier post talked about shaping the fairings for a better fit against the BT-60 main body tube.
After test fitting, I had to go back and do some more forming.

The instructions say to "use a 1/8" drill or some other solid round object to bend or round each fairing."

I used a sharpened dowel, it fit the conical end of the fairing better.
The BT-20 tube makes the fairing stiff, it takes some coaxing to get it right.



The inset picture shows the rounded side of a fairing.
Setting it next to the dowel shows the side arc.

The fairing on the right has been straightened.
 Get it as straight as you can.
For the best fit, wrap some 400 grit around a BT-60 tube and lightly sand the fairing.

You'll end up sanding the tip to about 1/2 the way down.
The sides of the fairing toward the wide end fit pretty well without much sanding.

Don't sand off the sharp point!
Sand a little and check the fit - repeat.




The fairing on the left hasn't been sanded.

The fairing on the right has been sanded, you can see the white edge all the way
around the fairing sides.
